Density: Typically around 2.4 - 2.8 g/cm³, the specific value may vary slightly due to the precise composition of the glass powder and the manufacturing process.

Particle size distribution: Can be adjusted according to different preparation methods and application requirements, commonly ranging from a few micrometers to several tens of micrometers. For example, D50 (the particle size when the cumulative particle size distribution reaches 50%) is typically around 10-30μm.

 Refractive Index: Generally between 1.5 - 1.6, this parameter is of significant importance for its applications in the optical field.

 Coefficient of Thermal Expansion: Generally within the range of (80 - 120)×10⁻⁷/°C, higher than that of common silicate glass. This is due to the addition of elements such as strontium, boron, and aluminum, allowing better matching and sealing with certain metal materials.

 Specific Surface Area: The specific surface area typically ranges between 1 - 10 m²/g. The size of the specific surface area affects the reactivity of the glass powder and its dispersion performance in composite materials.

Chemical Composition: Primarily composed of Strontium Oxide (SrO), Boric Oxide (B₂O₃), Aluminum Oxide (Al₂O₃), and Silicon Dioxide (SiO₂), with varying ratios depending on the specific glass formula. For instance, in common formulas, SiO₂ content may range from 40% to 60%, B₂O₃ from 10% to 20%, Al₂O₃ from 5% to 15%, and SrO from 10% to 30%.

Chemical Stability: Offers excellent chemical stability, with better resistance to acidity and alkalinity than ordinary silicate glass. In general acidic and alkaline environments, its corrosion rate is low, but inHydrofluoric AcidIn strong corrosive acids, chemical reactions still occur, leading to corrosion.

Solubility: Extremely low in water; almost insoluble. However, under certain conditions, it can partially dissolve or react in specific solvents or fluxes.
